3D printing is coming to space, thanks to a new experimental 3D printer which uses Gecko Gripper technology. The 3D printer mimics the way geckos cling to surfaces without falling, and could hold the solution to attach objects in zero gravity. The Gecko Gripper is being sent to the ISS in a Cygnus capsule aboard a United Launch Alliance Atlas 5 rocket launched on Tuesday. “If we had a choice of what we could use that printer for, I’m sure we could be quite creative,” ISS station commander Tim Kopra said.
